Window frame unit



INVENTOR d w a 9R W m L m M um 1M z M WITNESSES Patented Apr. 4, 1939 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to an improved window construction and has for an object to provide a window structure which will permit the outer sash to be placed in its correct position in the window frame or removed therefrom quickly and with safety to a workman.

Another object of the invention is to provide a window construction wherein an outer sash with suitable brackets and hangers is provided and arranged to permit the sash to be swung outwardly whenever desired or to be bodily removed or replaced.

A further object, more specifically, is to provide a window construction having a sash strip in a standard window frame with an outer sash formed with a beveled upper end fitting the sash top, the parts being associated with hangers permitting the ready mounting and demounting of the sash. 80 Reference is to be had to the accompanying drawing, forming a part of this specification, in

structure including the bracket, hanger and associated parts ready to be lnterengaged;

Fig. 5 is a front elevation of the bracket shown in Fig. 4;

Fig. 6 is a frontelevation of the in Fig. 4;

Fig. '7 is a detail fragmentary side view of the upper end of a modified form of bracket to that shown in Fig. 4.

Referring to the accompanying drawing by numerals, I indicates a standard window frame having a suitable parting strip 5 whereby the 4.3 sash strip 6 may be readily inserted in the outer part of a window frame. This strip is provided with a beveled surface 6' adapted to receive the beveled or inclined surface 2' of the'outer sash 2. The outer sash is bodily moved into the frame structure and is adapted to fit into the window frame H) shown in Fig. 1 when in fully functioning position. The sash 2 is provided with a hanger shown supporting hanger 4 which is provided with an opening I and a beveled surface 4". The edge 55 I is the meeting of the lower part of the surface 4" and the inner surface of the upper part of the hanger 4. As shown in Figs. 2 and 6, the upper part of the hanger 4 is oifset at 9 so that the sash 2 may fit'snugly into the frame I. as shown in Fig. 2. The hanger 4 coacts with a bracket 3 which is inclined upwardly and merges into an abutment 3', which in Fig. 4 is shown substantially triangular and which in the modified form shown in Fig. '7 is formed with an inclined edge Ill. The bracket 3 has an inclined smooth upper surface 8 so as to permit the edge 1 of the hanger 4 to slide easily on a thin knife edge portion when the parts are being shifted. The bracket 3 is provided with a base 3" which is secured to the window frame I by any suitable means, as for instance screws.

When the outer sash 2 is first mounted in place it may be moved to the position shown in Fig. 4 and then moved horizontally until it passes the abutment 3'. The sash is then lowered and the surface 4" engages the surface 8' and the hanger together with its outer sash slides downwardly at an incline until the surface 2' engages the surface 6' of the stop 6. The parts are then in their closed position, as shown in Fig. 2, with the lower end of the outer sash engaging the sill II.

The operation of my invention is as follows- The window frame I, having the angular outer sash stop 6, arranged directly over the sash 2, the sash supporting brackets 3, are fastened to the window frame I at the line where the top of the outer sash 2 and the window frame meet.

The outer sash 2, with its supporting hanger 4, having been arranged for their particular purposes as is common practice and not necessary to describe in detail. When placing the outer sash 2 in operative position it is elevated in a vertical direction until the top of the outer sash 2, bears against the lower portion of the supporting bracket 3.

The outer sash is then moved inwardly over the abutment 3' and then moved until the surface 4" of the hanger-4 rests on the supporting bracket 3.

As the weight of the outer sash 2 bears upon the supporting brackets 3, the angular form of the brackets causes the outer sash 2 to descend towards and into the window frame I and keeps the outer sash in its place by the force of gravity.

It will also be observed, that the supporting hangers 4 as they move downwards upon the supporting brackets 3, owing to the tapered form of the brackets, are gradually guided into a position as will cause the outer sash 2 to move readily into its place in the window frame I.

It will also be observed, that the abutment 3' of the supporting bracket 3, prevents the supporting hanger 4 from accidentally leaving the bracket 3.

When it is desirable to remove the outer sash 2 from the window frame I, the operation is the reverse to the above and is not necessary to describe.

While the outer sash 2 is closed, its weight is carried by the surface 4" of the hanger 4. When it is desirable to open the outer sash 2, the sash is moved outwards and its weight is taken by the edge 1 and as the sash 2 continues to move outward, the supporting hangers 4 bear upon the inclined surface 8 of the bracket 3, thus providing pivotal points upon which the weight of the outer sash 2 may move with little friction.

I do not desire to hold myself solely to the particular angularity of construction of the various parts or to the particular plane of movement, as described and illustrated in the drawing but desire to secure for myself the use of any angular construction of the parts and any angularity of the plane of movement that may be most desirable for the purposes described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A window construction consisting of a window frame, an outer sash, supporting-hangers and supporting-brackets, said window frame having in its upper part an angularly constructed outer sash stop, said outer sash having its upper edge constructed in angular formation and supporting-brackets having angular formation, said angular formation of all angularly formed parts having the same angular construction whereby the outer sash may be placed upon the supporting-brackets and supported thereupon and guided downward and inward in an angulardirection corresponding to the angular formation of the upper edge of the outer sash and the lower port on of the outer sash stop, until the outer sash is in its position in the window frame.

2. A window construction consisting of a window frame, a pair of supporting brackets secured to said frame and extending therefrom upwardly at an angle, an outer sash,-a pair of supporting hangers secured to the outer surface of the upper part of said outer sash, the upper part of said I hangers being offset outwardly, said hangers having openings in the upper part whereby they may be moved over said brackets for supporting the outer sash, the inclined position of said brackets causing said hangers to move downwardly at an angle until said outer sash fits in said window frame, said outer sash having a beveled upper end and said window frame having a parting strip, and a sash stop fitted against said parting strip formed with a beveled lower surface adapted to fit against the upper surface of said outer sash when the outer sash is fitted into said window frame.
